Description

Cloud-based Incoming Panel Integrated Supervisory Control System

The present invention relates to a switchgear monitoring control system, and more particularly, to a cloud-based switchgear integrated monitoring and control system.

With the technological development of computer networks, the existing computing environment, which relied on the independent hardware performance of each terminal, is in the form of Cloud Computing, which provides a corresponding service according to the request of the terminal by utilizing all computing resources on the network. Evolving.

The cloud service can be defined as an 'on-demand outsourcing service of computing resources' through an information and communication network such as the Internet. In a cloud environment, service providers provide services that users need by integrating data centers (cloud centers) dispersed in various places with virtualization technology. The user (client) provides necessary IT resources such as application, data storage, virtual computer server (hereinafter referred to as 'VM, Virtual Machine'), security, etc. Rather than being installed and used in the user terminal, the service in the virtual space is selected and used as many times as desired at the desired time.

Such a cloud service system builds a cloud center network composed of a plurality of cloud centers that provide services, and virtualizes computing resources in each cloud center and provides them to users. In the case of a rapid increase/decrease in data rate, it is important to create/move/delete the computing resources of each cloud center, ie, virtual machines, in real time.

Companies that provide cloud and virtualization services focus on providing smooth services to numerous virtualization server users, measuring resource usage during the time when the service is the most used, and providing the appropriate amount of resources. However, after business hours, resources provided in such a time frame consume unnecessary power due to over-allocation, which has a problem of aggravating the operation cost of the data center.

On the other hand, power demanding sources such as schools, buildings, apartment complexes and factories are equipped with a distribution board system to obtain the power required by each. Here, the switchgear system is a system that receives an extra high voltage, downs it to a low voltage, and then distributes it. It is a generic term for power equipment used for control, monitoring, and protection of the power system, and is also briefly referred to as a switchgear system. Failure of the switchgear system not only causes accidents such as damage, explosion, and fire of the power equipment, but also the load connected to the switchgear system, that is, the accident can spread to power demanding places such as schools, buildings, apartment complexes and factories. Therefore, the status of the switchgear system must be monitored at all times.

However, in order to diagnose the current status of the switchgear system, the power demanders where the switchgear system is installed regularly conduct off-line inspection methods such as circuit breaker opening/closing operation test, leakage current measurement, insulation resistance measurement, and contact resistance measurement. In order to implement such an off-line inspection method, the power equipment part of the switchgear system with a built-in circuit breaker must be separated from the grid power and then commissioned to an external professional company to carry out the operation, which puts a lot of burden on power demanders in terms of cost and time.

Recently, without the hassle and burden of such an offline inspection method, the online inspection method that enables the inspection of the circuit breaker by notifying the waveform of the signals indicating the operating characteristics of the circuit breaker to an external professional company located in a remote place online during the operation of the power equipment unit. have.

However, the current switchgear system has a problem in that the online method capable of managing and controlling the status of terminals or devices provided inside the switchgear is vulnerable to security problems such as data exposure in the process of data transmission.

The plurality of physical servers (PM) are servers of hardware resources composed of computing components such as CPU, memory, and storage.

The plurality of virtual servers (VMs) are servers implemented in software on each of the physical servers (PM) and operated independently or interactingly.

The cluster collection management unit 320 is a component that checks and monitors the resource surplus rate or the resource usage rate, and checks and stores the check at a predetermined time period (eg, 10 minutes, 40 minutes).

The resource quota means a CPU slack ratio of each physical server (PM), a resource (CPU) pool slack ratio, a physical server MEM slack ratio, a resource (MEM) pool slack ratio, etc., and the resource usage ratio is a resource (CPU) pool usage ratio and MEM) means the pool usage rate, etc. The CPU usage rate check is performed only on the physical servers in operation.

The cluster statistics management unit 330 refers to the stored information of the cluster collection management unit 320 checked and stored at a predetermined time period (eg, 10 minutes, 40 minutes), and the average of all physical servers (PM) constituting the cluster Detects CPU usage and average memory usage. The detected information is managed as data such as 10-minute statistics, full-day statistics, and same-day statistics.

The cluster control management unit 340 refers to the stored information of the cluster statistics management unit 330 and correlates the 10-minute statistics within the last hour with the 10-minute statistics for the same time zone the previous day. In addition, when the correlation-analyzed coefficient value is greater than or equal to the reference coefficient value (eg, 0.7), it is checked whether the resource usage rate according to the 10-minute statistics at the time of 1 hour elapsed from the same time of the previous day is less than or equal to the lower limit threshold. If the resource usage rate is less than the lower limit threshold, the cluster control management unit 340 determines that the cause is not due to the temporary performance of the physical server.

The cluster control management unit 340 is a component that manages and controls the power of each of the physical servers (PM) constituting the cloud system. The physical server (PM) with the minimum resource usage rate is powered off, and if the average of the resource usage rate is higher than the upper limit threshold, the physical server with the largest resource among the turned off physical servers (PM) is powered on (power-on) to manage the power in the cluster.

The cluster control management unit 340 monitors the stored information at different time intervals according to the purpose of management. For example, since overload of the resource usage rate is a problem that can be fatal to the system, the cluster control management unit 340 sets the average resource usage rate of the physical server (PM) at a relatively frequent time interval (eg, every 10 minutes) to the upper limit threshold. Monitor whether it is approaching or exceeding (eg 80%). On the other hand, when the resource usage rate of the physical servers (PMs) in the cluster is low (eg, 30% or less of the lower limit threshold) or when you want to prevent unnecessary power consumption by the physical servers, the time period is relatively long (eg, 30 minutes apart). Monitors the average resource usage rate of the physical server (PM).

The cloud control center 110 includes a plurality of clusters (resource pools) constituting the cloud system, the cluster control management unit 340 , the cluster statistics management unit 330 , and the cluster collection management unit 320 for managing each cluster. ) to control

As described above, the present invention periodically checks the resource (resource) usage rate of the physical servers in the resource pool, and powers off the surplus physical servers when the actual detected average resource usage rate is remarkably low, and the resource pool When the average resource utilization rate in the pool increases beyond the upper limit threshold, the power-off physical server is turned on to use the resources in the pool more efficiently and consume it for physical server operation. power cost is reduced.
